Using API performance to display basic web vitalies.

API performance is a set of standards for measuring and evaluating performance using JavaScript. It can be imagined as a box that contains the same functionality for Core Web Vitals reports and the overall performance statistics that you will receive in many tools for performance testing.

🚀 API interface of performance is extremely large and contains many different interfaces, properties and methods. Although most of them are supported by all major browsers, Chromium -based browsers are the only ones that support all CWV properties.

💡 There are two main ways of obtaining performance indicators that are interested in: using the Performance.getiate () method or using a PERFORANCEBSERVERVERVER.

• 📌 Performance API allows you to evaluate the loads of items on the page and in real time to display Core Web Vitals metrics.
• 📌 You can use the Performance.getntries () or PerformanceobServer specimen to obtain performance metrics.
• 📌 Performance API allows you to measure very specific things, but also supports the properties that are reflected on CWV metrics.
